title: Late complications following the arterial switch operation.
abstract: The arterial switch operation has been the principal treatment for transposition of the great arteries and its variants for the last 25 years. Early mortality has decreased significantly over time, but long-term complications include pulmonary artery stenosis, coronary artery obstruction, neoaortic valvar insufficiency, arrhythmia, and aortic arch obstruction. This article provides an overview of the history, anatomic patterns, surgical results, and possible operative solutions discussed in the literature for patients with transposition of the great arteries who undergo arterial switch operations that result in late complications. Published journal articles were identified through PubMed literature search. The authors selected 72 articles for analysis. It is concluded that modifications can be made to the arterial switch operation in an effort to meet the challenges presented by late complications.
